This seems like a dumb question; but I wonder if one can use tcpdump to view the decrypted out flow from and esp tunnel?
I have an established tunnel on machine 'firewall'. The tunnel is a route between net 10.128.10.0/24 and 192.168.10.0/24. 'firewall' has 192.168.10.1 as the ip on its internal interface. When I ping 10.128.10.1 using 192.168.10.1 as the source address, I can use tcpdump to view the esp packets via the external interface. Is there a way to use tcpdump to view the packets as they traverse from the tunnel to 192.168.10.1? I had no luck attaching tcpdump to the internal interface. By the same token, can I hook any of the traffic with ipfw? I suspect that if any of this traffic were leaving the machine, I would see it; but maybe not if 'firewall' itself is the destination? Thanks for your time. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
